Add weight behind the wheels and that lifts the other side, think seasaw - add a second kid to one side and the other side becomes lighter, some of the weight is transferred.
Adding ballast on the pin transfers all of that weight to the pin and truck. Adding balast between the pin and wheels distributes the additional weight to both the pin and wheels.
I don't think that's what he's asking. His measurements show that he already understands how the balance works. I believe his question was, "What can I do to move some of my weight in front of the axles?"
